If you can't do that (don't have one available), then run a portscan from http://www.linux-sec.net/Audit/nmap.test.gwif.html, it will tell you if your machine is actually allowing connections to 25 from the outside (net) interface, rejecting them. Note: if your firewall is dropping, not rejecting connections this scan can take up to 15 mins to complete, just hang tight. Also, you only have to specify the port number _or_ name in the rules file. I notice you have both smtp and 25 listed, not sure if that will have any bad effect. In addition to trying what Jeff Potter said, if the MTA is listening, try to send a mail from your system to your system, i.e. From:[EMAIL PROTECTED] To:[EMAIL PROTECTED] It won't access the outside net at all. /eli > PORT(S) DEST > ACCEPT net fw tcp > http,https,55555,ssh,6665,6666,6667,6668,6669,7000,4899,imap,pop3,smtp,25 > - > ACCEPT masq fw tcp > >domain,bootps,http,https,631,imap,pop3,smtp,nntp,ntp,6665,6666,6667,6668,6669,7000,25 > > - > ACCEPT masq fw udp > >domain,bootps,http,https,631,imap,pop3,smtp,nntp,ntp,6665,6666,6667,6668,6669,7000,25 > > ------------------------------------------------------- This sf.net email is sponsored by:ThinkGeek Welcome to geek heaven. http://thinkgeek.com/sf _______________________________________________ courier-users mailing list [EMAIL PROTECTED] Unsubscribe: https://lists.sourceforge.net/lists/listinfo/courier-users
